Mixed bag

Definitely a helpful tool for working with BLE Devices but I’ve been having issues lately where it’s not reading characteristic values for some reason. Please update!

We need macros in iOS version

I love your app, I personally think is good and it works properly, but we would love to have macros as we do have in the android version. Thanks

Crashing fixed as of v1.8.6

Looks like this was the same issue others were having (#27 on gh), latest update seems to have addressed it. @nordic, thanks for the quick fix, sorry I wasn’t more responsive with crash dumps, was out of country for a few weeks, glad others were able to help debug.

The app immediately crashes and closes when opening. iOS 11.3.1, iPhone 8
